Buildozer remote
|
|
================
|
|
|
|
.. warning::
|
|
|
|
This is an experimental tool and not widely used. It might not fit for you.
|
|
|
|
Pack and send the source code to a remote SSH server, bundle buildozer with it,
|
|
and start the build on the remote.
|
|
You need paramiko to make it work.
